The document discusses equine gastric ulcers, including risk factors, signs, diagnosis, and treatment and prevention. Some key points covered include that gastric ulcers are common in horses, especially racehorses and show horses, and can develop within 5 days of stressful conditions. Signs may include poor appetite, weight loss, or behavior changes. Treatment involves pharmacologic agents like omeprazole, natural remedies, dietary changes like increased forage and limited grains, and management changes to reduce stress. Preventive measures include probiotics, limited grain intake, and constant access to hay.

Understanding Equine Ulcers and Gastric Health What are gastric ulcers? Risk factors Signs Diagnosis Treatment and prevention
Some statistics . . . It has been well-documented that as many as 90% of racehorses and nearly 60% of active show horses have gastric ulcers. Simulated conditions representing activities typical in the recreational use of horses were determined to cause gastric ulcers in as little as five days . McClure SR, Carithers DS, Gross SJ, Murray MJ. Gastric ulcer development in horses in a simulated show or training environment. J Am Vet Med Assoc. 2005 Sep;227(5):775-777.
What are Gastric Ulcers? Gastric = stomach Ulcer = erosion Equine Gastric Ulcer Syndrome (EGUS) Ulcers can also occur in the colon but we will not be discussing these as the history, signs, diagnosis and treatment are all different
A horse in his natural state Grazing 20+ hours per day
Risk Factors for Gastric Ulcers Diet Infrequent hay feeding High grain diet Feeding horses more than five pounds of grain every five to six hours can cause gastric ulcers. ~Frank M. Andrews, DVM, Univ. of Tennessee
Risk Factors for Gastric Ulcers Limited turnout Stall confinement Lack of grazing time Lack of socializing time
Risk Factors for Gastric Ulcers Intense exercise
Risk Factors for Gastric Ulcers Stress Training/competition Transportation Schedule changes Injury or illness
Risk Factors for Gastric Ulcers Excessive use of NSAIDS
Signs of Gastric Ulcers Physical Mild, recurring colic Weight loss Poor appetite Dull hair coat
Signs of Gastric Ulcers Behavioral Poor attitude Irritability Resistance Dullness
Signs of Gastric Ulcers Poor performance Lead swapping Reluctance to bend/collect Hitting jumps Slower times Lack of energy
Signs of Gastric Ulcers None (silent, subclinical)
Diagnosis of Gastric Ulcers History Signs Endoscopy Response to treatment

Treatment and Prevention of Gastric Ulcers Goal is to create a permissive environment in the stomach for tissue healing, which requires a combined approach: Pharmacologic agents Natural agents Dietary changes Management changes
Treatment and Prevention of Gastric Ulcers Pharmacologic agents Proton pump inhibitors (FDA-approved) GastroGard速 (Rx) UlcerGard 速(OTC) Both contain the active ingredient omeprazole Histamine type 2 receptor antagonists Cimetidine Ranitidine
Treatment and Prevention of Gastric Ulcers 2. Natural agents Antacids: calcium, magnesium and aluminum Amino acids: glutamine, threonine, glycine, collagen Herbs: licorice, marshmallow root, slippery elm, aloe vera, adaptogens Others: pectin, lecithin, silica, gamma oryzanol, kaolin

Treatment and Prevention of Gastric Ulcers 3. Dietary changes Provide constant access to good-quality hay Or, provide hay frequently throughout the day Offer alfalfa hay, if possible Limit the amount of grain Or feed grain in small, more frequent meals
Treatment and Prevention of Gastric Ulcers 4. Management changes Give down time from competition, travel Provide pasture turn out, with buddy if possible Keep a regular schedule Reduce stress
Questions
Your Questions: Should you feed supplements to "prevent" ulcers? If so, what would you recommend? Does one dose a day of Gastrogard act as a preventative for ulcers? Someone has told me that Ulcergard can actually cause ulcers when the medicine is discontinued is this true? How do you help reduce causes of ulcers when you are in a boarding situation? I heard music playing in a barn can cause ulcers in horses-is this true? How do probiotics factor in prevention/symptom management of ulcers? Bute and ulcers... should you give ulcer preventive along with meds? Is grinding of my horses teeth a symptom of ulcer pain? Can ulcers be caused by bacteria as in humans - H. pylori and is there a treatment for same?
Your Questions: I have read many articles that alfalfa hay is a great way to naturally buffer the acid in the stomach. How much do you recommend giving a day and how often? Does sweet feed really cause ulcers? Are there natural alternatives to treat ulcers? My horse was fighting pneumonia and taking alot of meds. While adding Ulcergard in the morning, I also added Zantac at night to prevent colic or ulcers. The Ulcergard is very costly, but I was very nervous about his stomach and had to do something. Your thoughts? What do wild roaming mustangs do to support their gastric health? Does it make sense to go to the expense of scoping (particularly if you have to travel a long distance to get this done) for definitive diagnosis? Can you discuss ranitidine and sucralfate, as well as compounded omeprazole?
